In this comprehensive guide, we’ll walk you through everything you need to know to successfully sell your Dexcom G6 transmitter.

Understanding The Dexcom G6 Transmitter

The Dexcom G6 is a small, wearable device that continuously monitors glucose levels in real-time, transmitting data to a compatible receiver or smartphone app. It consists of a sensor, transmitter, and receiver, allowing users to track their blood sugar levels without the need for fingerstick tests.

The Dexcom G6 transmitter plays a crucial role in this system, as it wirelessly communicates with the sensor to collect glucose data and transmit it to the receiver or smartphone. Each transmitter has a limited lifespan, typically lasting around three months before needing replacement. As a result, Dexcom G6 users may find themselves with surplus transmitters after upgrading or switching to a different system.
